The last part of the book is suggesting some tools to evaluate a website. Since the book is in print and not all tools live forever you’ll find current tools on this page. These tools I use myself.

If something is missing, or if you’d like to ask a question just hit me up on Twitter on @marcusosterberg or use the contact form. Thanks!
